We recently purchased brand new 10 units of Cisco 9115AXP and 1 unit of Cisco 3504 Wireless controller.
The issue is, some of the Apple laptop (both MacBook Air and Macbook Pro) users couldn't see the SSID and if they see and connect, the connection is intermittent.
It works for a while and then auto-disconnects. After that, if we try to connect, it doesnt connect at all.
Then, we have to turn wifi OFF and then wait for a while and then it connects. Sometimes, if it still doesnt connect then we have to restart the laptop.
This is super frustrating as we have around 10-15 users impacted with this issue.
Some of the mac's are on MacOS Catalina and some of them are still on MacOS Mojave.
We tried talking to Cisco support but they didnt helped and asked to update Wireless drivers. I have never seen Wireless drivers update for Apple laptops ever.
Appreciate if you experts can give me some lead that where we might be missing out.
Hi, I am having similar issues on MacBook Pro with the Cisco 9100 series AP. My users intermittent connectivity. My issue is that users will drop during their Webex, Zoom or Team's meeting. A bit strange as audio and video will continue to stream, but audio and video will not "upload" and pings to gateway and 126.96.36.199 would stop. However, user can still hear and see the video from others on the video conference call.
I have similar issues with production environmet running 17.3.1ES01 on Windows 10 machines. Windows freeze for some seconds and drops connection, and after 3 minutes it reconnects again. But I have notice the same in a couple of iPads as well.
From user point-of-view is more noticiable when on a remote meeting, but it always use to happen close to the re-auth timer defined on the WLAN so we have raised that timer to 15h.
I have tested many Intel drivers and that doesn't solve the issue.
The symptom I've observeed is the device losing its IP address and sending 7 DHCP Requests, and then restarting the process and sending DHCP Discoveries. After that time it start to receive the DHCP Offers, with the last one been the ACK'ed.
Opened a TAC case and we are investigating on the many AP catures, OTA and Win10 traces.
If that is the same behaviour, I will share our findings.
